How to do it

Tap on a table with a wooden spoon. Hear it?

Now, put your ear right up against the table and tap.

How does it sound? Louder?

When your ear is on the table, you hear the sound travel through the table, when you stand up, the sound has to travel through the air and this makes the sound seem not as loud as when you hear it through the table.

Now try this. Put an alarm clock on the table and listen to its ticking. Quiet, huh?

Now, try listening to it by putting one end of a yardstick up against your ear and the other end touching the alarm clock. Louder, huh?

Look around your house and see if you can find other objects to listen through.
